Hello
My customer chosen TPS2H160-Q1 for their product ( Proto-type stage)
They are testing for current limit opearation and thermal shutdown operation.
Would you please kindly check attached ppt and give me your advice?
I myslef did not check by EVM.
Question
Q1 I think step(A) ~(B) ST2 goes low is due to current limit.
The difference between actual( 2.3A) and setting ( 1.8 A) seems to be
due to current is slowly ( a 200~300ms/ step )increasing like as other thread(*)?
Please have your opinion. (*)
Q2 I think step(D) Io kept ~0.7A is ICL(STD)=60% of external current
limit setting . ( I don’t know the reason why 0.7A).
Is it correct? Please have your opinion.
Q3 I think (D) to (E) is current limit during thermal shutdown,
but we see dithering during ( D) to (E).
I don’t know whether dithering is inherent during thermal shutdown
Is this inherent for TPS2H160-Q1?
Please advise.
Best Regards
